Ultra RapidWarm™ Blast
Maintain stable results in a fraction of your time.
Description A single medium for ultra-fast warming of vitrified human blastocyst-stage embryos.
Application Ready to use after warming to 37 °C in ambient atmosphere. Works with all cleared vitrification solutions and devices.
Storage Store dark at +2 to +8°C. Media bottles can be used for up to 2 weeks after first opening. Use aseptic technique and minimise the time outside the refrigerator.
- Purpose: For warming of vitrified human blastocyst stage embryos.

Improve workflow without compromising clinical outcomes
While vitrification revolutionised embryo cryopreservation in IVF, it is still labour-intensive. Consequently, users have been seeking to streamline the workflow with a consistent, efficient procedure.
Ultra-fast warming of blastocysts
Recently, the golden standard of using a multi-step warming process has been challenged. Several publications have shown that blastocysts can be warmed in a much faster way, in just one warming step.
The studies demonstrate that single-step ultra-fast warming is comparable to multi-step standard warming in terms of survival, re-expansion, and clinical outcomes with the added benefit of saving time1, 2, 3.
In addition, studies present that blastocysts warmed in a low sucrose medium show a tendency for faster re-expansion4 and shorter time to hatching5.
New product innovation with an ultra-fast warming protocol
Ultra RapidWarmTM Blast is a single medium for warming of vitrified human blastocyst-stage embryos. The medium contains 0.25 M sucrose to remove membrane-permeable cryoprotectants and gradually rehydrate the cells.
Ultra RapidWarm Blast contains 20 ml of warming solution, delivered in 4 bottles of 5 ml. Each bottle can be used for 2 weeks after first opening, if using aseptic techniques and minimising the time outside the refrigerator.

How to warm blastocysts with Ultra RapidWarm Blast
Preparation
Place at least 0.5 ml and up to 1 ml of warming solution into a dish and warm to 37 °C.
Warming
Leave the blastocyst in the solution for 2 minutes.
Washing
Wash the blastocyst several times with culture medium, or transfer medium such as EmbryoGlue®, then incubate until further use.
“The implementation of short rehydration during warming in our blastocyst cryopreservation program was easy to implement and is a game changer in many ways: Foremost it is a time saver; supporting an even more efficient workflow in our daily schedule.
On top of this, allowing blastocysts to reach their physiological intracellular milieu after fast warming allows them to regain their cellular functionality sooner, which is reflected in better outcomes such as higher ongoing pregnancy and, lower miscarriage rates11.”
- Juergen Liebermann, PhD, HCLD Director Laboratories Fertility Center of Illinois, USA
“As time-efficiency is a critical parameter in busy IVF labs, the recent onset of the ultrafast warming procedure was definitely a great opportunity that we decided to explore immediately.
This was obviously extremely simple to implement, and it rapidly confirmed its expected capacity to reduce time and to ensure smooth workflow, while providing perfectly stable and maintained clinical outcomes, as confirmed by more than 2 500 warmed blastocysts”.
- Professor Thomas Freour Head of Infertility Department & ART Centre University Hospital of Nantes, France
High lot-to-lot consistency ensures high performance
Vitrolife’s Mouse Embryo Assay (MEA) go beyond regulatory demands, using multiple endpoint assessments, including blastocyst cell number, with narrow acceptance levels to ensure high performance and the best results for the customers.
Vitrolife has unique competence in testing, which is performed in-house to maintain full control with traceability of each released product.
